Abstract

The paper focuses on promising topologies and control strategies to meet strict power saving and efficiency requirements over wide output power range demanded by new regulations and trends in data and telecommunication industry. The optimal control algorithm for phase shifted ZVS DC/DC converter is described implemented in new IC controller. Some practical design recommendations are provided allowing zero voltage switching at all operating conditions. The advantages of suggested control strategy are verified by test results based on 95.3% efficient, 12-V, 660-W output DC/DC converter for server power supply.
